[00:00:00]The wood frog freezes solid each winter.

[00:00:03]Its body temperature drops to 20 below zero.

[00:00:06]Ice crystals [music] form inside its blood and organs. Its heart stops beating. Its lungs stop breathing. For months it's completely frozen. [music] Imagine that. Then spring arrives and the ice melts.

[00:00:20]The frog's heart begins to beat again.

[00:00:23]Its brain sparks back [music] to life.

[00:00:26]It opens its eyes. It stands up and hops away.

[00:00:30]Biologists call this controlled [music] hypothermia. The frog produces glucose and urea that acts like natural antifreeze.

[00:00:39]They protect its cells from tearing apart as ice crystals form. No other vertebrate can survive this. Frogs do [music] it every year and somehow they walk away from it.
